One thing that people fail to realize is that inevitably the space inside the AR world is subdivided into a series of flat screen-like spaces. So really the big win of AR is that you now have many monitors. maybe 10 or more, which is an improvement over the typical laptop user who has 1 tiny screen or maybe 1+ 1 larger external monitor. The additional screen space is 90% of the win. The fact is that most computer information is not interact-able spatially. Imagine for example, a spreadsheet. Each cell contains typically numbers or text, neither one of which would be manipulable by squeezing, pinching or any other hand gestures one can devise. Sifting, sorting are tasks that are amenable to AR, but frankly the hundreds of millions of Excel users will see this demo and go "meh". I predict the big win is in medical training, and repair of complex machinery. The military has got to love this, because they have super expensive stuff that they want 20 year olds to fix in a hurry with minimal training. For game programming AR might be great for level design, but realistically, one must notate the logic via text, and notating in a sloppy AR environment will be more of a hindrance than a help. AR will be essential for a few tasks, but remain niche for the vast majority of tasks.
